lasikennot

Lasikennot is a Finnish term that translates to "glass cells" or "glass compartments" and typically refers to the cellular structure found in certain types of glass, particularly those formed through processes like foaming or as a result of specific chemical treatments. These structures are essentially microscopic voids or bubbles within the glass matrix, which can influence the material's properties.

The formation of lasikennot can occur during glass manufacturing. For instance, in the production of foam glass, a blowing agent is added to molten glass, which decomposes at high temperatures, releasing gases that create a cellular structure upon cooling. This results in a lightweight material with excellent thermal and acoustic insulation properties.

In other contexts, lasikennot might refer to the presence of small, trapped pockets of air or other gases within conventionally manufactured glass. These can arise from impurities in the raw materials or imperfections in the melting and forming processes. While often considered defects, in some specialized applications, controlled formation of these micro-cells might be utilized to modify optical or physical characteristics. The size, distribution, and gas content of the lasikennot can significantly impact the glass's density, strength, thermal conductivity, and refractive index.
